RESUMO
The paper is concerned with the effect of diets including three chemically different types of the "Ocean" paste on biochemical characteristics (glycolysis, the content of phosphofructokinase, dehydrogenase, glucoso-6- phosphate, demethylase, dimethylalaniline hydroxylase, ascorbic acid) of the liver of rats exposed to sodium fluoride overdosage. The test diets were compared with those containing conventional sources of protein (casein, beef). Acute exposure to sodium fluoride caused changes in the biochemical characteristics. The most appreciable changes were seen in the group of rats fed beef. As compared with control, the shifts in the biochemical characteristics were negligible provided the rats exposed to acute and chronic poisoning received the diet supplemented with the paste. No morphological changes were found in the internal organs. The data obtained indicate that the type C "Ocean" paste has a protective action in sodium fluoride poisoning.
